go to Block diagram>>functions palette>> applications control>>quit LabVIEW

By passing a 'true' boolean to this function, you can quit/ close the application/LabVIEW

So when you want to close your executable, include code to pass a true boolean to this function on your Block Diagram

If the window name never change, you can use lvwutil32.zip (you can download it from NI) to Quit Application.

If the window name is not available, try ExtApp at:

Hi,


See this thread:

The attached vi (by me) does the job.

Wiebe's method works.  But it's a little bit "brutal".  Should be used as last resort.  If you search Microsoft for "teminating a process", you will find they recommand other methods.

NI's VIs, on the other hand, provide a nice way to close other applications.

Sending a windows message is nicer. But it won't work on command line programs. Do you have any idea what method NI use?

Are you sure about this?  I just tried to close DOS windows (command prompt and cmd.exe), works fine.

NI's method uses Windows message.

Could be, never tried it. My guess is that sending the message to a dos program closes the Window it's in, just like closing it by hand.


Have you tried to close a running DOS program that is not running in a window? For instance if it is started with System Exec? Perhaps windows makes a hidden window for it, so it might still work...


If the program is not responsive (hanging), sending the message won't work (?). In any other case, sending the message is more decent.


Regards,


Wiebe.

For hang window, send message won't work for sure.  Terminate process would be a good choice.

But be aware that it terminates the process right away.  The process won't even get a chance to close the dll its calling.
